Python 从模块中的类调用而不指定其名称
我可以像导入模块一样从模块导入类吗Python 从模块中的类调用而不指定其名称,python,import,Python,Import,我可以像导入模块一样从模块导入类吗 from module_name import * 这样我就不必在每次需要变量时都指定“module.class”名称了 示例： 在模块中： class SomeClass: var1 = "Hello" var2 = "Bye" 在主脚本中： def print_something(text): print(text) if __name__ == "__main__": print_something(var1)
from module_name import *
在模块中：
class SomeClass:
var1 = "Hello"
var2 = "Bye"
def print_something(text):
print(text)
if __name__ == "__main__":
print_something(var1) # "module_name.SomeClass.var1" should not be necessary, only "var1"
class RGBcolors:

您可以为此使用元编程：
class GlobalNamespace(type):
def __init__(cls, name, bases, dct):
type.__init__(cls, name, bases, dct)
globals().update({n: v for n, v in dct.items() if not n.startswith("__")})
class RGBcolors(metaclass=GlobalNamespace):
...
注意：请阅读对您的问题和答案的评论，解释为什么这在原则上是个坏主意。不要将类视为模块。它们是两个不同的概念。类在逻辑上不同于模块（尽管它们有一些相似之处，比如提供封装）。您不能从类导入！将数据保留在变量名称之外例如，这意味着您不应该使用名为
